When have you made a mistake delegating tasks to your team members?

"Earlier in my career I would delegate tasks at random, thinking that everyone had the skills to complete any company-related task. I found that these employees would procrastinate on these tasks if they seemed overwhelming or if they did not understand them. After a bit of time, and some learning, I began to delegate based on personality type and skill-set. This method proved to be much more effective, and I follow this delegation style to this day."

"I am usually cautious when delegating tasks because putting the wrong person in the wrong function can be a dangerous, and expensive, mistake. A few years ago I put an employee on the incorrect piece of machinery, thinking that he was certified in operating that bit of equipment. I am now sure to double check credentials before delegating."
